[recycled sixtie]

2012 Ford Ranger(6 cyl) with 10k miles which he bought new a year ago. So it is one year into a 3 year warranty. He has a daily leak(diameter the size of a coffee mug) of oil coming from the engine.
Ford dealership has replaced gaskets and has been their 3 times but the problem is still there. Anybody have a Ford Ranger with this of problem? I suggested keep on going back to dealership. He is not happy with it and talks about selling it. I said that he would take a big hit in depreciation. It would have been $15k more for a similar sized Toyota truck. Any suggestions on the fix?
